The arrival of rebellious, red-headed young Percival Blake at Billabong immediately puts the whole household on edge. How does Percival find his name changed to 'Bill'? And how does he become drawn into perilous adventure in the rocky ranges? His escapades fill a few memorable weeks of summer, in the course of which Billabong gains a new adopted son, and no-one has time to feel the least bit lonely.
